Wholesale original Mada. Explosion normally open type gas emergency shut-off safety valve

Features M16 / RM NA series valve is a normally open solenoid valve type pulse trigger, with accidents and self-locking manual reset function. 1. The valve is in their daily work normally open solenoid valve coil is powered off, do not consume energy. 2. When the accident occurred, the instantaneous valve coil is energized, triggered quick closing valve, and into the self-locking state. In this case, even if the power is removed, the valve is still in the lock off, will not re-open automatically. 3. When the workers finished with accidents, labor re-open the valve, the gas supply would be restored. Structural analysis diagram (a): The illustrated :( a) 1.

Manual reset bolt valve body open and close Identification: 1) DN15 ~ DN50 diameter electromagnetic valve is a manual reset lever stroke to identify the valve is opened and closed. (As shown): 2) DN65 ~ DN300 diameter electromagnetic valve is OPEN arrow with manual reset valve head screw (hexagonal pattern) on the (open) into a horizontal line to identify whether, if the valve is compared to a horizontal line on, otherwise the valve is in the closed state. (As shown): Parameter Control type: direct-acting operation for the media: non-corrosive gases structure gas, natural gas, liquefied petroleum: Diaphragm seal valve seat maximum working pressure: 0 ~ 500mbar; 0 ~ 6bar Nominal : PN16 Open: manual reset type off time: <1 second (approximately 20 msec) Connection: threaded connection (1/2 \ "; - 2 \";) comply with EN10226 standard flange interface (DN40-DN300) in line with ISO7005 Standard power supply voltage DC12V, DC24V, AC220V / 50HZ Electrical connection: plug-in or casting a body (regardless of positive) Explosion levels: EExmIIT4 shell protection grade: IP 65 adapt to temperature: -20 ℃ - + 50 ℃ Medium temperature: ≤80 ℃ Seal Material: NBR dingqing rubber Voltage Tolerance: -15% - + 10% Body material: Die-cast aluminum alloy operating parameters: continuous pulse output or metal inner parts: stainless steel and brass installation specifications and precautions: 1. Usually you want to install On the main supply pipe being monitored zone chamber. 2. The pipe cleaning or purged, as there is solid contaminants in the media, it is recommended to install a filter on the valve before the pipeline. 3. strict installed in accordance with the valve body the subject of the gas flow direction. 4. Recommends that the valve horizontal or vertical riser installation. 5. When the solenoid valve open-air installation, you must install a protective cover, in order to ensure the performance and extend its life. 6. The solenoid valve coil, plug-ins and connections, non-hitting impact, to avoid damage. Gas Equipment Co., Ltd.
